KNIFE FOR MINCING-MACHINES.

Application filed January '7, 1909.

To all whom it may concern:

Be it known that I, ALEXANDER GoMoRY, subject of the King of Hungary,residing at Budapest, Empire of Austria-Hungary, have invented new anduseful Improvements in Knives for l /lincing-\ Iachines, of which thefollowing is a specification.

This invention relates to a knife for use with mincing machines.

According to the invention the blades or arms of the knife are providedwith two cutting edges and can be easily detached and secured inposition, whereby the grinding of the cutting edges can be effectedquickly and with facility. The blades are mounted in such a manner thatthey are securely reoperation.

T he accompanying drawing illustrates one form of knife made accordingto the invention.

In the said drawing :Figure 1 is a plan view of the knife, and Figs. 2and 3 are transverse sections respectively on the lines AB and C-D Fig.1.

The lower knife is integral with the annu lar boss and is provided withblades 2, 2, the cutting edges of which are on opposite sides of theknife. Between the boss and the blades there are arranged projectingribs 3, 3 forming a bearing in which the boss 4 of the second knife isintroduced. This knife is placed at an angle to the knife 1, 2 and is soarranged that the downwardly projecting ribs 6, which are locatedbetween the oppositely directed cutting edges 5 and the bossSpecification of Letters Patent.

4, are applied against the sides of the lower boss. The knives are bythis means rigidly secured in place but can be easily removed for thepurpose of grinding, so that no special devices are necessary for thispurpose.

A further advantage of the two-part knife consists in the fact that incase one of the blades should fracture it is only necessary to detachand replace one of the knives whereas in the case of a single bladeknife a fracture renders the whole of the knife useless.

I claim as my invention 1. A mincing machine knife comprising a air ofarms or blades disposed in the same plane each having oppositelydirected cutting edges, bosses integral with the said arms, and ribsbetween the cutting edges of the blade and the bosses, the ribs of onearm interlocking with the boss of the other arm, substantially ashereinbefore described.

2. A mincing machine knife comprising in combination, companion armseach provided with two knives, said arms being disposed in crossrelation and lying in the same plane, having interlocking membersadapted to hold said arms in prescribed relation with respect to eachother.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

ALEXANDER GOMORY.
